IBM's Stock Soars Due to Quantum Computing Progress

Shares of International Business Machines Co. are having their best day since January, driven by optimism around the company's quantum-computing efforts.

IBM is known for its various technologies, but its quantum efforts have been gaining attention. The company announced a plan in June to build the world's first large-scale, fault-tolerant quantum computer by 2029, paving the way for practical and scalable quantum computing.

A soon-to-be-published IBM paper discusses progress made in quantum error correction using an AMD chip. According to a report by Reuters, the algorithm developed by IBM to enable error correction can run on chips made by Advanced Micro Devices Inc. (AMD).
